Triangulating only cells of type VTK_CONVEX_POINT_SET is actually more difficult than it sounds. All non-triangular faces will be split into triangles. If there is any neighbor cells that share these faces, they will also have to be split in some way to keep the interfaces consistent. The splitting can then easily propagate to the neighbors' neighbors and so on.

However, I'm not too clear on how ParaView handle's these cell types, but I can worry about that another time. It would be nice to have an option in Save Data to output all cell types equal to VTK_CONVEX_POINT_SET as tetrahedrals, or a filter for identifying and isolating these specific cells and tetrahedralising them. My workaround for today involved tertrahedralising the whole mesh, which increased its size 7-fold so not the most practical option. =================================== Adriano Gagliardi MEng PhD Project Scientist Computational Aerodynamics Aircraft Research Association Ltd.
